545774eb88 serial/pci_16550: make sure that interrupts are disabled during init 
Make sure that interrups are disabled during initialization.
This is a proper fix for an unexpected MSI interrupt for PCI serial driver.

d4bbbe0d0b drivers/pty: support pty write to send signal, like serial driver 
The interaction between the shell service in adb and adbd occurs through a pseudo-terminal (pty).
so, when a command is launched through adb shell from a PC, users now have the ability to pause
or kill the launched,application by inputting specific commands CONFIG_TTY_SIGTSTP_CHAR or
CONFIG_TTY_SIGTINT_CHAR, akin to the capabilities provided by nsh.

ceb2921d79 drivers: prepare 16550 UART driver to support PCI 
prepare 16550 UART driver to support PCI:

- [breaking change] change argument of uart_ioctl() from `struct file *filep` to `FAR struct u16550_s *priv`
  Also fix moxart_16550.c build related to this change

- [breaking change] change argument of uart_getreg() and uart_putreg from `uart_addrwidth_t base` to `FAR struct u16550_s *priv`
  Also fix arch/x86/src/qemu/qemu_serial.c and arch/x86_64/src/intel64/intel64_serial.c related to this change

- [breaking change] change argument of uart_dmachan() from `uart_addrwidth_t base` to `FAR struct u16550_s *priv`

- move `struct u16550_s` to public header

- generalize UART_XXX_OFFSET so we can use it with any register increment

- make u16550_bind(), u16550_interrupt(), u16550_interrupt() public

- remove arch/or1k/src/common/or1k_uart.c and use common 16550 MIMO interfacve

- change irq type in `struct u16550_s` from uint8_t to int to match MSI API

1. read/write memory
2. Use watchpoint,breakpoint,single step.
    use up_debugpoint api

3. Ctrl+c to stop, continue, or single step.
    hold uart send and receive

4. register a panic event, when crash or assert/panic, we use uart to
